go to file > publish settings > flash, then make sure under audio stream that it's set to these settings: MP3, 56 kbps, Mono. it doesn't have to be set to mono, but that's what I have mine set to... I suppose if you have audio that is louder in 1 speaker than in the other, you would set it to stereo...

Because you didn't set the sound quality right.
Go on file > publish settings and then go on the flash tab.
On the flash stream, go and select ADPCM 44hz 5 bit for the stream part. There should be a drop down letting you do that.
